Versioning: [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Added
- "Scan image" button next to the input pane: opens the phone's rear camera (or a file picker on desktop), runs OCR locally in the browser via Tesseract.js (loaded from esm.sh on first use), and replaces the editor contents with the recognised text. Language follows the "From" dropdown via an ISO 639-2 mapping; "Auto-detect" loads a common European set (`eng+por+deu+nld`). Progress status shows beneath the input ("Loading OCR engine…" → "OCR 40%" → "OCR done in 3.2s"). Zero image-size cost — same CDN pattern as CodeMirror.
- Images are downscaled to 1600 px on the long edge before OCR. A 12 MP phone photo (~4000 px) drops to ~1.3 MP, making Tesseract 4-8× faster with no real accuracy loss for printed text. Smaller-than-1600 px inputs are passed through unchanged.

### Fixed
- "Hot: …" status no longer claims "unloads in X" when the server's `keep_alive` is `-1` (Ollama returns an absurd year-4001 `expires_at`). Threshold: any expiry >7 days drops the suffix and just shows the model name.

## [0.2.0] - 2026-06-09

### Added
- Vim bindings in the input via CodeMirror 6 + `@replit/codemirror-vim` (loaded from esm.sh, no build step). Supports `i`/`Esc`, `hjkl`, word/line motions, `dd`/`yy`/`p` (vim's internal register), undo/redo, `/` search, `:` command line. Auto-disabled on touch devices (detected via `(pointer: coarse)`) where modal editing fights the virtual keyboard.
- `Shift-H` / `Shift-L` cycle focus across the page controls (source → target → model → editor → button) like `Shift-Tab` / `Tab`. Also overridden in vim normal mode (replacing vim's viewport-top/bottom default) so the same shortcut works to leave the editor.
- On page load, the model dropdown defaults to whichever model Ollama already has hot — skips the 5-15 s disk-reload pain on the first translation. After load it follows the user's manual selection.

### Changed
- Editor font-size pinned to `1rem` to match the output pane (CodeMirror 6 ships smaller by default).

## [0.1.0] - 2026-06-09

First release. Stateless translator UI that proxies streaming requests to
Ollama on radagast.

### Added
- FastAPI backend with three endpoints:
  - `GET /api/models` — filtered (`gemma,aya` by default) list from Ollama's `/api/tags`
  - `POST /api/translate` — streams Ollama's NDJSON `/api/generate` response back to the browser
  - `GET /api/loaded` — proxies Ollama's `/api/ps` for the currently-loaded model
  - `GET /healthz` — for Kubernetes probes
- Single-page UI:
  - Source / target / model dropdowns (30+ languages, "Auto-detect" source)
  - Token-by-token streaming into the output pane with a blinking caret
  - Live status line: spinner while waiting for first token, pulsing dot during streaming, elapsed time and token count
  - Glowing border on the output pane during streaming
  - Loaded-model indicator (`● ` prefix in dropdown, "Hot: … — unloads in Xm" status line); refreshes on page load, on translation completion, and 500 ms after typing pauses
  - ⌘/Ctrl-Enter to translate from the input
  - Dark mode, inline SVG favicon (Star of Fëanor)
- Dockerfile: two-stage `uv` build, slim Python 3.13 runtime
- `build.sh`: multi-arch (amd64 + arm64) manual push to Scaleway, tags `:latest`, `:<git-short-sha>`, and `:<pyproject-version>`
- Cluster deploy via the `valinor` repo at `apps/finrod/` (bjw-s app-template, internal-only ingress at `finrod.jpnadas.xyz`)

### Fixed
- Lock against public PyPI explicitly — the workstation's global `uv` config had pointed `uv.lock` sources at the dexterenergy private artifact registry, which 401'd inside Docker
